Question

ratio of two adjacent sides of parallelogram if 2:5 and its perimetre is 56 m find length of its adjacent sides​

Answer 1

Step-by-step explanation:

perimeter of a paralleleogram = 2 ( a + b )

we know a = 2x and b = 5x

56 = 2 ( 2x + 5x )

56 = 2 ( 7x )

14x = 56

x = 56/14

x = 4

adjacent sides a = 2x = 2 × 4 = 8

b = 5x = 5 × 4 = 20

Answer 2

Answer:

Length of adjacent sides is 8m and20m

Step-by-step explanation:

let the adjacent sides be 2x and 5x

then,

2(2x + 5x) = 56m

2*7x =56m

7x = 56m/2

7x = 28m

x = 28m/7

x = 4m

So 2x = 2*4m = 8m

5x = 5*4m = 20m
